10.5 Compressed air connection
WARNING!
Compressed air must be free of oil and humidity.
Contamination of compressed air may result in a poor
cartridge filtration, decreased cleaning and reduced life time.
Purge the compressed air line to remove any debris prior to
connecting air line to the dust collector air tank.
Shut off the compressed air system and purge all air lines
prior to servicing or maintaining the collector.
•
Locate the pneumatic air tank behind the MAXITOP dust collector.
•
Connect air line to the tank using pipe seal. Check for possible leak(s).
Note :
the use of an air dryer is strongly recommended to avoid any problem related to humidity in
the compressed air system. Install a shut off valve, pressure regulator and filter on the compressed
air line. Those components are not supplied by A.Q.C. unless required by the customer. All
components must meet a maximum 90 psig pressure.
NEVER ALLOW MORE THAN 100 PSIG.
Damages to components may occur.
10.6 Electrical connections check and initial start-up
1 .
Ensure all electrical connections are sealed and current flows to the panel.
2 .
Ensure remotre controls (if ordered) are properly wired and breakers are OFF.
3 .
Remove objects away from air inlet or fume arm hoods.
4 .
Switch breaker to ON.
5 .
Switch the starter to ON and shut it OFF immediately. Check for proper fan rotation by looking
at arrow on the motor.
Note :
excessive air volume may shorten the filter life or cause an electrical surcharge to the motor
or electrical system.
11 MAGNEHELIC GAUGE
The Magnehelic is a differential pressure gauge used to measure the pressure differential of the
cartridges. This allows a visual reference on the filters status and indicates when it is time to
replace.
This gauge is generally factory installed unless under specific request to A.Q.C. If the Magnehelic
gauge is not part of the collector, connect the
(HIGH-PRESSURE)
tube on the "dirty" side of the
collector. Connect the other
(LOW-PRESSURE)
tube on the "clean" side of the collector.
This gauge is not available when the collector is supplied with a DCT-1000 electronic board and a
DCP pressure module since it is this one that will read the pressure differential.
